Are you sure it's not just something that was spilled on the headers? Leaked brake fluid, oil, coolant, ect will stink very quickly after the engine is started, even if it was wiped off. Headers warm up very quickly to 5-600* which is plenty to cause this.

cold and hasn't been run in a couple years. There would be a fair bit of crap in the pipes.
I don't think there's anything on the pipes, it smells like very hot metal, not anything else.

Get an IR thermometer and see how hot they really are. You might be just fine. Like Grey said, and since the bike has been sitting, may just be rusty valve seats not sealing well. A little seafoam and some WOT usually cures that ;). Valve lash OK? Too tight of a valve would do this. Also retarded ignition timing can makes pipes hot enough to glow.

That just gave me an idea for a cheap test, hold the throttle about 1/2-3/4 for a bit, if it takes about 30sec for them to start glowing then you're good any less than that means trouble....

Note: they make great cigarette lighters in a pinch, my buddy uses the pipe on his quad all the time

Wait what what? Everything is fairly self-explanatory..my gixxer is running lean,which makes the pipes instantly super hot, and I having to pull the SV battery out in order to test it.

I'm putting off pulling the carbs. I really don't wanna do this
